RADIATGR.

Application med May 10,

T o all whom it may/'concern Be it known that I, ARTHUR B. MoDrNn, acitizen of the United States, residin at Racine, in the county of Racineand tate of Wisconsin, have invented certain new and useful Improvementsin Radiators, of which the following is a description.

My invention belongs to that general class of devices known asvradiators which are generally used on automobiles, trucks, tractors andthe like, in connection with the cooling systems of internal combustionengines. The invention has amon 1ts ob]ects the production of a deviceof t e kind described that is simple, durable, convenient, eicient,attractive and satisfactory for use wherever found applicable. Manyother objects and advanta es of the construction herein shown andescribed will be obvious to those skilled in the art from the disclosureherein' given.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like orcorresponding parts, l

Fig. 1 is a view in elevation of embodying my invention;

Fig. 2 is a sectional view taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken substantially on line 3-3 of Fi 1;

F1g. 4 is an enlarge view of the lower radiator tank;

Fig. 5 is a view in elevation of a slightly modified construction; and

Fig. 6 is a sectional view taken substantially on line 5-5 of Fig. 5.

Referring to the drawings, 1 represents a chanibered part or tank ofsuitable size, shape and material, which is preferably provided witli aninlet pipe 2 to which a hose a radiator pipe or the like may be attachedconnecting the same with the cooling system. As shown, part 1 is alsoprovided with a tubular part 3, the same constituting the filler tube oropening similar to the constructions now in use.

Associated with the part 1 is a chambered part 4 communicating withthepart 1, and the two forming substantially a tank consisting of twocommunicatin parts. Associated with the part 4 isa c ambered part 1920.Serial No. 380,214.

5, which constitutes what may be termed `a lower tank. As shown,extending between and connecting the tanks are the desired number oftubes 6 through which water or other cooling fluid may pass from thetank 4 to the tank art 5, and in so doing, be cooled by the air passingor drawn between the tubes. Fins or plates 7 of a desired form, arepreferably arran ed on the tubes so as to increase the radiating areaand defleet the air. The part 5 is provided with an .outlet, as shown,through the pipe 8, which may be connected to a suitable part in thesystem from which the fluid is to be cooled.

In the construction shown in Figs. 1 and 3, the tank parts 1 and 4 areprovided with openings 9 and 10 which register with each other, a gasketor the equivalent` 11 being arranged between the two, and the parts aresecured 'together by bolts 14 of which there may be any desired number.As shown, what may be termed a spider 12 is arranged at each of theopenings 10, the same being preferably secured on the inner side of thetank part 4, and of a size and material sufliciently ri id so as not toyield. The part 1 is recesse as at 13, and the bolts 14 positioned withtheir heads in the recesses and extended through the tank 1 through theopening in part 15 of the s ider 12, the central part 15 of the spidereing preferably threaded to engage the bolt threads. I have shown. thetank parts 4 and 5 secured together by the bars 16, so that there issubstantially no strain on the tubes 6. -To support or carry theradiator, I provide a U- shaped frame consisting of the side parts 17connected at 18, which parts 17 are preferably secured to the upper tank1 in any suitable manner. The frame may be secured in place, whendesired, or supported by means `of the lugs 22. Referring particularlyto Fig. 2, one or more springs 19 are shown arranged between frame part18 andthe tank, the tank 5 being preferably provided with a flange 20and the cross part 18 of the frame with the fiange 21, between which isarranged the springs 19. Obviously these springs supplement the sidebars 16, and also take considerable strain from the bolts 14, due to theweight of the parts and contained liuid, and they give some resiliencyor flexibility to the construction in case of jars, strains or twisting,so that leaks about the ends of the tubes and between the tanks areobviated. The radiator tank and framey parts, at the front side, may becovered by a cover plate 23, secured to the frame 17--18 by bolts,screws, or in any other referred manner, (not shown), the cover p ate,however, being open or cutaway at 24, so as to expose the tubes 6. Thiscover plate 23 ma'y be large enough to cover the top of the tank andsides and bottom, lif so desired. In the construction shown, however, Ihave merely arranged the same over the front. Part 1 and the frameconstitute a unit part and parts 4 and 5 constitute another unit.

As is most clearly shown in Figs. 2 and 4, the discharge pipe 8 may beso connected to the tank 5 that it may be easily detached by working atthe front of the radiator. In the construction shown, a spider 12 isarranged on the tank part 5 and the outlet pipe 8 is provided with aspider 8', 11 being a gasket arranged at the opening from the tank. Theparts are secured together by a bolt 14 extending through the spiders 12and 8 and to the front side of the tank part 5. The tank may bereinforced by the rods 24 spacing the spiders 12 apart so that the tihtening up on the bolt and the drawing o? pipe 8 tightly against thetank will not cause the collapse of the tank. The construction issubstantially similar to the connection between the tank parts l and 4.It will be noted that by removing the bolts 14, 14 and 14', the radiatormay be quickly dissembled and the tubes and plates taken out for repairor replacement.

In the slightly modified construction shown in Figs. 5 and 6, 25represents a tank part having the inlets 26 and 27, the same beingprovided with the flange 28. A cooperating tank part 34, fianged as at29, is

rovided, the parts being secured together y bolts 33', or theequivalent, extending through the fianges. Obviously tank part 34 may beof any desired size. If only a flat plate having an opening through, itwould serve as well. If desired, a gasket 32 may be arranged as shown.Depending from the tank part 34 are tubes 30, on which may be arrangedthe plates 31. Arranged at the lower end of the tubes 30, is a tank 35having an outlet 36, the tanks being connected together by the side bars37, or the equivalent. In this construction I provide a frame 38-39-38,which is secured to the end fianges on part 25, by boltsl 33', or theequivalent. Springs 4() or the equivalent are arranged between the framepart 39, and the tank 35, similar to the construction previouslydescribed and serve to relieve strain in the bolts 33. The frame isprovided with the flanges or lugs 41, by means of which the radiator maybe secured in place and su ported as desired.

n the construction shown in Fig. 1, water or other cooling fluid entersthe pipe 2 from n will be noted that with both of ches@ i constructionsthe radiator consists of two associated tanks connected by-tubes and anassociated chamber part or tank connected to one of the other tanks` allof the parts being suitably secured together. The parts 4 and 5 andtubes may be standardized in various sizes, as may also be the parts 34and 35 and tubes, and the parts 1 and 25 may be varied in contour, sizeor capacity, depending upon the particular automobile or the like uponwhich the radiator is to be used. On the other hand under thecircumstances, parts l and the frame and 25 and the frame may bestandardized, and the radiator eement consisting of the two tanks andconnecting tubes, may be modified or varied for ditferent makes of cars,depending upon the preference of the manufacturer thereof. Tariouscombinations are therefore possible with either construction, in case itis desired to repair the radiator tubes or parts, the tanks 4 and 5 andtubes, or 34 and 35 and tubes may be removed from the top tank parts andframe without removing the entire assembly. This is of considerableadvantage in some cases, as where manufacturers y use a standardizedpart 1 or 25 and frames, the tanks and connecting tubes may beinterchanged with another of the same type whenever desired.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing from.the spirit of my invention; hence I do not wish to he understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described, or uses mentioned.
